Since I decided to work in the collage technique, it is necessary to take into account the specifics of copyright when working with other people's photographs. The Cut and Glue community has put together a compilation of free-to-use resources for collagists.
Working with sound
List of musical themes
1 - Intro + final family tune (1st piece) Calm, introductory. Perhaps: the sounds of nature, the sounds of the house. Speed: Slow, increasing slightly towards the next scene. For the closing version - decreasing in speed and sounds.
2 - Round dance + acquaintance (2nd piece)
Smooth or abrupt transition from the first theme. Loud, cheerful, dynamic. Speed: fast, slowing down at the moment of acquaintance. Possibly: instruments, sounds of nature, voices, dances, bells.
